Specific answers for teams replacing Synder with GatewayFee Studio.
Never just add 2.9% + $0.30 to your invoice, because Stripe charges 2.9% on the added fee too. Use the algebraic reverse gross-up formula: Gross Charge = (Target Net Amount + $0.30) / (1 - Total Fee Rate). For a $1,000 net payout at 2.9% + $0.30, charge ($1,000 + $0.30) / 0.971 = $1,030.18.
Stripe's 2.9% + $0.30 rate applies only to domestic cards in your settlement currency. If an international buyer pays with a foreign card (+1.5%) in another currency (+2.0% FX conversion) via a hosted Stripe Invoice (+0.4% to +0.7%), the combined fee reaches 6.8% to 7.1% + $0.30.
No. Neither Stripe nor PayPal refunds the original processing fee (2.9% + $0.30 or 3.49% + $0.49) when you refund a customer order—meaning a refunded $200 international order costs you up to $13 in sunk gateway fees.
Standard US Stripe card processing is 2.9% + $0.30, while standard PayPal Checkout is 3.49% + $0.49 (and 2.99% + $0.49 for standard credit/debit fields). On a $100 domestic order, Stripe costs $3.20 vs $3.98 on PayPal Checkout.
Never. GatewayFee Studio runs 100% locally inside your browser memory. Your transaction CSVs and client invoices never leave your device.
While Synder ($65+/mo) and Bookkeep charge recurring monthly subscriptions with strict transaction tier limits, GatewayFee Studio is a one-time $19 lifetime buyout for unlimited local batch fee auditing and reverse gross-up calculations.
